Thought maybe that someone in the video booth was being funny and overlaid an image they found on the internet as a last "Fuck you!" before being shit-canned, but alas, I cannot find that collection of images anywhere.

Which means to me that someone took the time to put that together in order to deliberately show to all who was watching.

How many of these symbols would someone now associate, subliminally, with the imagery of the baseball game they were watching now?
